v1.4.1

sfxEnergyInOut

sfxEnergyInOut(theAhu, dates)

Compare Temperature Differential to SiteMeter's Energy

- Requires
`zone air temp sensor`

point on equip,`weatherPoint temp`

, and`siteMeter`

needs`energy`

point - Side Effects: None
- Input: equip (usually
`ahu`

) with`zone air temp sensor`

and`dates`

- Output: kWh / deltaTemp hisGrid
`read(ahu).sfxEnergyInOut(pastMonth)`

sfxFourier

sfxFourier(hisGrid, filter: null, theChartType: "bar")

Plot duration vs frequency

- Works on booleans or lambdas of other kinds such as numerics
- Must only have 2 states (forced by lambdas)
- Only works on a single ts and a single v0 column
- Side Effects: None
- Input: ts, v0 grid
- Output: Transmuted history grid of ts, v0 columns
- Filter used appears in col meta data
`read(cool).hisRead(2016-07).sfxFourier`

sfxHisDurPlot

sfxHisDurPlot(hisGrid, delta: 0%, dur: 16min, theChartType: "scatter")

Plot duration bucket vs frequency

- Percentage and Duration thresholds determined manually or automatically
- Supports a true History Grid with multiple V columns
- Side Effects: Data interpolated, multiple histories that do not start and/or end around same time will result in leading and trailing 0s
- leading and trailing 0s and length of entire window will affect results in auto mode
- Input: ts, val*n grid where val*n can be multiple V columns with only numbers
- Output: Transmuted history grid of ts, V*n columns
- delta and dur used appear in column meta data
`read(temp and discharge).hisRead(yesterday).sfxHisDurPlot`

`read(temp and discharge).hisRead(yesterday).sfxHisDurPlot(50%, 16min, "bar")`

`readAll(temp and discharge).hisRead(yesterday).sfxHisDurPlot`

`readAll(temp and discharge).hisRead(yesterday).sfxHisDurPlot(50%, 16min)`

sfxHisNoiseFilter

sfxHisNoiseFilter(hisGrid, delta: 0%, dur: 16min)

Remove low duration events

- Percentage and Duration thresholds determined manually or automatically
- Supports a true History Grid with multiple V columns
- Side Effects: Data interpolated, multiple histories that do not start and/or end around same time will result in leading and trailing 0s
- leading and trailing 0s and length of entire window will affect results in auto mode
- Input: ts, val*n grid where val*n can be multiple V columns with only numbers
- Output: Transmuted history grid of ts, V*n columns
- delta and dur used appear in column meta data
`read(temp and discharge).hisRead(yesterday).sfxHisNoiseFilter`

`read(temp and discharge).hisRead(yesterday).sfxHisNoiseFilter(50%, 16min)`

`readAll(temp and discharge).hisRead(yesterday).sfxHisNoiseFilter`

`readAll(temp and discharge).hisRead(yesterday).sfxHisNoiseFilter(50%, 16min)`

sfxHisShowNoise

sfxHisShowNoise(hisGrid, delta: 0%, dur: 16min)

Remove high duration events

- Percentage and Duration thresholds determined manually or automatically
- Supports a true History Grid with multiple V columns
- Side Effects: Data interpolated, multiple histories that do not start and/or end around same time will result in leading and trailing 0s
- leading and trailing 0s and length of entire window will affect results in auto mode
- Input: ts, val*n grid where val*n can be multiple V columns with only numbers
- Output: Transmuted history grid of ts, V*n columns
- delta and dur used appear in column meta data
`read(temp and discharge).hisRead(yesterday).sfxHisShowNoise`

`read(temp and discharge).hisRead(yesterday).sfxHisShowNoise(50%, 16min)`

`readAll(temp and discharge).hisRead(yesterday).sfxHisShowNoise`

`readAll(temp and discharge).hisRead(yesterday).sfxHisShowNoise(50%, 16min)`

sfxMode

sfxMode(src, binsOrInterval: 1)

Find One or More Modes for Dataset

- The interval parameter determines what range constitutes the same number
- Only works on a single ts and a single v0 column
- Side Effects: None
- Input: ts, v0 grid and the interval used for the groups (ie 1 treats 1.50 to 2.49 as 2 and so on)
- Output: List of dicts as string which can include multiple modes (if two or more numbers appear the same number of times)
`read(temp and discharge).hisRead(pastMonth).sfxMode`

`read(cool).hisRead(pastMonth).sfxMode`

`read(power).hisRead(pastMonth).sfxMode(2)`

sfxMultiFourier

sfxMultiFourier(theList)

Plot multiple Fourier grids together

- All input grids must come from sfxFourier()
- Works on booleans or lambdas of other kinds such as numerics
- Side Effects: None
- Input: Multiple Fourier grids
- Output: Multiple v columns
`sfxMultiFourier([read(temp and discharge).hisRead(2010-01).sfxFourier(x=>x<60),read(temp and discharge).hisRead(2010-01).sfxFourier(x=>x>80)])`

sfxNumbDist

sfxNumbDist(hisGrid, binsOrInterval: 10, theChartType: "bar", raw: true, forceInterval: false, forceCleanStart: false)

Plot bins vs frequency

- Also shows average and total duration in designated bin
- Works on booleans, numbers, and strings
- Only works on a single ts and a single v0 column
